For the first moment, John held his ground. But soon the carnage even had him pull back a step. Not enough to avoid the blood splatter, but that didn't bother him at all. The smell that the rendering caused made him nearly turn back to his own feast, but he settled for running a hand down his cheek and licking the blood from his finger, eyes never leaving the mess. Eric would probably be furious.
When the other seemed finished, and spoke to him again, he chuckled.
"Fast, yes," he agreed. He gazed down at the mess, but he was truly full for the first time since he could remember, and walking through the mess. Had his family enjoyed this kind of carnage before? Yes, most assuredly. It made him jealous, but all the more appreciative. He wasn't one to let to this way, and the demon in him reveled.
"If it isn't impolite to ask, what manner of creature are you? The lore I'm familiar with from my worlds never mentioned anything so..." He paused but couldn't find a single word to describe the sight before him. He settled for the smile of a well fed beast, and a simple hand gesture towards the black being's form.
